Ivan Fyodorov

Ivan Fyodorov or Ivan Fеdorov sometimes transliterated as Fiodorov, was one of the fathers of Eastern Slavonic printing. He was also a skilled cannon maker and the inventor of a multibarreled mortar. Fyodorov was forced out of Moscow because of his attempts to employ the “blasphemous” new printing techniques, and found refuge in Poland-Lithuania, first in Zabłudów, then most notably in Ostroh, where he was instrumental in the publication of the Ostrog Bible.
